best is so subjective. it just depends on what you like, as most, or should i say many, teas: green, oolong or black, make excellent iced tea. if you like a bit of sweetness try a flavored tea. jasmine tea iced is delicious.
for oolong teas, i prefer the nuttier, more roasted. they taste great iced.
something similar but much better quality to your present lipton iced tea may be a ceylon tea.
there are also several ways to brew iced tea. a good way to find out what you like is do a bit of reading on the subject, take a look at some tea websites, and then experiment. there are also sample tea packs especially for iced tea.
